SpoonFTP FTP bounce attack
| spoonftp-ftp-bounce (7943) |  Medium Risk |
Description:
SpoonFTP is vulnerable to an FTP bounce attack using the PORT command. In an FTP bounce attack, the FTP client specifies a different IP address than its own to trick the FTP server into making a connection and sending data to another host on the network. This creates the appearance that the computer is being probed or attacked by the FTP server when in fact it is the FTP client that is indirectly attacking it.
Platforms Affected:
- Pi-Soft Consulting, SpoonFTP 1.1.0.1 and prior
Remedy:
Upgrade to the latest version of SpoonFTP (1.2 or later), available from the Pi-Soft Web site. See References.
Consequences:
Bypass Security
